Globe valve, unlike the ball valve, works on the principle of the movement of the shaft, which moves up and down and has a plug (also called disc or plug) at its end, in order to regulate the fluid passing through the valve. Globe valves are generally suitable for use as regulating valves. While ball valves operate parallel to the fluid, globe valves operate perpendicular to the fluid.
Globe valves are suitable for use as regulating valves and their working principle perpendicular to the fluid provides ease of use in lines with high pressure.
The basic parts of globe valves Hendwell are body, disc and cover.
In globe valves, friction losses are high because the fluid changes direction within the valve. Additionally, although they are suitable for use as a regulating valve, when left at intermediate levels the disc is constantly exposed to fluid load, leading to wear and tear.
